TO ALL WHOM IT MAY CONOERN:

Be it 4known that I, ERNST V. JEINSEN, of No. 32 East Fourth street, in the city, county, and State of New' York, have invented a new and improved Self-Detaching Car-Coupling; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable those skilled in the art to make and use the same, reference being had to the accompanying drawing, forming part of this specification, in which- Figure 1 represents a sectional sido elevation of this invention.

Figure 2 is a plan or top view of .the same, some parts being broken away to expose` the working parts of the coupling..

Similar letters of reference in both views indica-te corresponding parts.

This invention relates to a car-coupling, the coupling pins oi' which are hinged to their rods, which at the saine time may be made to support the buffers. These rods are free to slide back and forth in suitable guides, and they are held in position by springs, and the coupling pins are provided with `shoulders which catch under suitable lips or stops in such a manner that the `coupling pins will remain in ail-upright position unless exposed to a lateral strain, and consequently the "shackle-bar is retained and the cars are prevented from getting uncoupied as long as all the cars remain on the track. But if one of the ears runs oif the track, whereby the coupling pins forming its connection with the succeeding car are vsubjected to a lateral strain, one or both of said coupling pins turn down and the cars become detached. I

A A represent two adjoining cars which are coupled together by the shackle-bar B. This shackle-bai' is made in theordinary form or shape, and it catches 'over `the coupling pins C C', which are hinged to rods D D', as clearly shown in iig. 1 of. the drawing. Said rods slide back and forth in rsuitable guides or cages E E', which are secured to the under surfaces ofthe platformsof the cars, and to their outer ends may be attached the buffers F F', which arc constructed in anysuitable manner. The top-plates of the cages E E form lips a a', which project over shoulders b b on the coupling pins, and retain the same in an upright position, as shown in the drawing. The position of the rods D D in their cages, and consequently that of the coupling pins in relation ,to the lips a a', is governed by the action of springs c c* c 'c*, which also may act as the buli'er springs. The

tension of the springs is regulated by nuts d did 01, and it will be readily understood that by screwing up the nuts d d .and unserewing the nuts d* d*, theV power which retains the shoulders of the coupling pins underA the li s a a is increased, and vice versa', and b these means the Vower re uired to ti the cou lin ins over P Y P q P P g P and release the shackle-bar can be regulated at pleasure. .As long as both cars remain on the track the coupling pins are retained in an upright position, either by the lips a aor by the strain of the shackle-bar itself, and

the cars are not liable to become uncoupled spontaneously. But if one of the Ycars runs oif from the track, the

coupling pins C G are exposed to a lateral strain, whereby one or the other or-both become disengaged from their lips-aor a', so as to turn on the rods D or D', and consequently the shackle-bar is released and the cars are uncoupled. By this arrangement many serious accidents. will be prevented, since if the engine or any of the cars is thrown ofi' the track it will detach itself from the succeeding cars and the balance of the train will be saved. Y

What Ivclaim as new, and wish to secure by Letters Patent, is i 1. The hinged coupling pins C C', provided with shoulders b 6', in combination withv lips a a', and with the shackle-bar B, constructed and operating substantially as and for the purpose described.

2. The adjustable springs e c*, in combination with the coupling pin C, shoulder b, and lip a, constructed and operating substantially as and for the purpose set forth.

This specification signed by me this 7th day of January, 1867.
